Patent GB-656133-A (GB)
Title: Improvements in temperature responsive means for actuating temperature regulators
IPC: G05D23/12
Filed: 1947-02-10
Abstract: 656,133. Temperature-responsive actuating elements. FULTON SYLPHON CO. Feb. 10, 1947, No. 3878. Convention date, April 3, 1946. [Class 64(ii)] [Also in Group XXIX] In a temperature-responsive mechanism, a temperature control member, e.g. a valve 15 for controlling the flow of heating medium through a car heater, is actuated above a predetermined temperature by a pair of thermostatic systems oppositely connected to said member, each system having a charge of fluid, e.g. butane or isobutane, which follows the temperaturepressure characteristics of a saturated vapour, see curve 42, Fig. 2, below the predetermined temperature, see point 43, so, that the control member is not actuated until the temperature rises above the predetermined temperature, when one of the opposed charges follows the characteristics of a gas, see curve 44. In the form shown, the valve 15 co-operates with a port 14 in a partition 13 of a housing 10 through which flows a heating medium. Bellows 16, 26 are connected to either side of the valve member which is biassed to an open position. The liquid charge in the temperature-responsive system of which one bellows 16 forms a part, is partly vaporized, and the pressure in this bellows therefore follows the law of saturated vapour with response to temperature change. The other bellows 26 has a liquid charge which is entirely vaporized at a temperature a little below the temperature at which the valve member operates, see points 45, 46, so that above this temperature, at least, pressure in this bellows follows normal gas laws. The containers 23, 33 of the temperatureresponsive systems, with which the bellows 16, 26 are in communication, are both exposed in the space of which the temperature is to be controlled. The volume of the system including container 33 may be adjusted by a screw 38 which expands or contracts a bellows 35 to determine the temperature, see point 43 or point 47 for example, at which its charge is completely vaporized. At a slightly higher temperature the difference between the pressures, represented by the distance between points 45 and 46 or points 49 and 50, is just sufficient to overcome the bias of the valve member and close the port. At a still higher temperature, the fluid charge in the system of bellows 16 may be completely vaporized. A stop member 20 limits the extent to which bellows 16 may be collapsed on cooling. The Specification as open to inspection under Sect. 91 describes the use of differing volatile liquids in the two opposed systems and also the use, in the adjustment system including bellows 26, of a charge of gas such as air having the pressure represented by the point 43 at the temperature at that point. This subject-matter does not appear in the Specification as accepted.

Feb. 5, 1930, No. 3896. [Class 36.] In order that oil may penetrate more easily in one direction than in the reverse direction through the paper insulation of an electric cable, the fibrous structure of the paper is loosened at uniformly spaced points by pressing small round pointed tools into one of the surfaces of the plain paper, indentations 1 with a central pinhole 3 and conical projections 2 on the other side of the paper being thus formed. The paper is then spirally lapped on the cable and impregnated. It is stated that the spacing effect of the projections 2 assists longitudinal distribution of the oil between the paper layers. The cable insulation may consist partly of indented paper and partly of plain paper.

Title: Electric fuel pumps
IPC: F02M1/00
Filed: 1939-03-07
Abstract: 528,843. Electric diaphragm-pumps. STEWART-WARNER CORPORATION, and WHITTED, J. B. March 7,1939, No. 4081/40. Divided out of 527,552. [Class 102 (i)] [Also in Group XXXV] The working stroke of a diaphragm fuel-pump is performed by the armature of an electromagnet having a main switch in circuit with an actuating-coil. At the end of the return stroke or beginning of the working stroke, the actuating-coil is shunted across the main switch, and the latter is held closed, whilst at the end of the working stroke, the circuit of the actuating-coil is closed to open the main switch and thereby break the circuit of the electromagnet. The circuit shown in Fig. 7 includes an electromagnet 98 for actuating an armature 74 connected to the pump-diaphragm, switches B, A co-operating with the armature, a main switch Z comprising contacts 108, 110, and an electromagnet 112 consisting of separate high-resistance coils 127, 128 for operating the contact 110. The contact 108 is connected by leads 123, 136 to the ignition-switch 122, and the contact 135. The contact 110 is connected by leads 124, 125 to the electromagnet 98. The leads 123, 124 may be connected by a high resistance. The coil 127 is connected by leads 129, 130 to the leads 123, 125, and the coil 128 is connected by leads 131, 132 to the lead 123 and the contacts 134, 133. When the ignition-switch is closed, the armature 74 raises the pump-diaphragm, and the contacts 134, 135 open but do not break a circuit since they are normally shunted through the switch Z. When the armature engages the contact 133, the coil 128 is energized, the switch Z is opened, the electromagnet 98 is de-energized, and the armature is moved downwards by the spring- actuated pump-diaphragm. When the armature closes the contacts 134, 135, the coil 128 is energized to neutralize the coil 127, the switch Z closes, and the cycle is repeated. In a modification of the above-described circuit, the contacts 134, 133 are connected through two resistances or a single resistance to the leads 125, 124, the coil 127 is connected to the contact 133 and the ignition-switch, and the coil 128 is connected to the contact 135 and the ignition-switch. When the armature breaks the contacts 133, the current through the coil 127 is not cut off but is caused to pass through the electromagnet 98, sparking at the contact being thereby prevented. In the circuit shown in Fig. 17, a single-coil magnet 160 is employed for operating the contact 110. The coil is connected by leads 161, 162 to the ignition-switch 122, and the contacts 163, 140 of the switches B<SP>1</SP>, A, and the lead 124 of the contact 110 is connected by a lead 142 to the electromagnet 98, and through a resistance 165 to the contact 164. Specification 527,624, [Group XXXVII], is referred to.
